I have been tryiong to buy the Single Edition today but when I clicked on the "buy" button then there is an error message says "We are currently experiencing technical difficulties. Please try again later." Anybody knows what's wrong with it??

I have the same problem and have been trying to buy a Single Edition license since last Thursday (Apr 5).

I chatted with an Adobe sales rep through the online store this morning. They told me to call an 800 number, which I did. I was then transferred to another department where I was put on hold for 25 minutes with no answer before I had to give up.

Can anyone with Adobe advise as to when the Single Editions will be for sale again?

Or is this a bad move and we should wait for the new content viewer to be approved at Apple before trying to submit a Single Edition to the app store?
